Battery Adapter+ Cold Shoe Mount For Rollei 35SE/35TE (Replace PX27 with LR44)

This adapter enables your Rollei 35SE/35TE to use 4 pieces of LR44 (or SR44), instead of PX27, which is difficult to buy and expensive.   Though more expensive, SR44 is slightly better than LR44, as SR44 has a more stable voltage. Ideally, you should use 4 pieces of 1.4V 675 zinc air battery, so you can get 5.6V, exactly what the Rollei 35SE/35TE needs. But using 4 pieces of LR44 (or SR44) is fine.  You can still use PX27 battery with this adapter.
